IMPROVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No. 56,525, dated July 24, 1866.

To all whom it may concern Be it known that I, EsEK BUssEY, of the city of Droy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in (looking-Stoves, of which the following is a full and exact description, reference being had to the accompanying drawings, in which 'Figure 1 is a side elevation; Fig. 2, a rear elevation; Fig. 3, a plan; Fi 4, a vertical section at the line 2 2; Fig. 5, a front view of a section at the line y y, and Fig. 6 a top view of a partial section at the line a; oc-all of a cooking-stove embodying my said invention, like parts being marked by the same letters in all the figures, and the arrows therein being indicative of the courses in which the gases of combustion pass through the stove.

One part of my invention consists in making a cooking-stove with a culinary boiler or hot-water reservoir arranged opposite to one upright side or end of an oven, and with a fire-flue extended from under or along the oven, under or across the bottom of the said boiler or reservoir, and from there up along that upright or lateral outer portion, side, or end only of the reservoir or boiler which is not nearest or immediately opposite to the oven, and into a draft-pipe or exitpassage for the gases of combustion, so that the gases of combustion, in passing from under or along the oven to the draft-pipe or exit-passage, shall be confined and made to pass through the said extended fire-flue, first, all under or across and in contact with the bottom of the said boiler or reservoir, and from there wholly up along and in contact with that upright outer surface, side, or end only of the boiler or reservoir which is not nearest or immediately opposite to the oven.

In illustration of this part of my invention, the aforesaid drawings represent a cookingstove having an oven, A, a culinary boiler or hot-water reservoir, B, open at top, with a movable lid or cover, 0, and arranged opposite to the upright rear side or end, d, of the oven, and a fire-flue, E E, extended from under the bottom f, or from along the rear end, d, of the oven, under or across the bottom g of the boiler or reservoir, and from there up along that upright outer surface, side, or end, It, only of the reservoir or boiler which is not nearest or immediately opposite to the oven, and into a draft-pipe or exit-passage, I.

By thus making the gases of combustion, in their passage from under or along the oven A to a draft-pipe or exit-passage, I, to all surely pass under or across and in contact with the bottom 9 of the reservoir or boiler, and from there up along and in contact with that upright outer surface, it, of the boiler or reservoir which is not nearest or immediately opposite to the oven, the excess of heat in such escaping gases is applied so as to insure the heating of the bottom and outer portion of the reservoir or boiler more strongly, and thereby secure the heating of the whole body of the water in the boiler or reservoir to a more uni form temperature from top to bottom, and with less disengagement or escape of steam from the top of the water than if the gases of combustion, in passing from under or along the oven to the draft-pipe or exit-passage, were allowed to rise up along and in contact with that side j of the boiler or reservoir which is nearest or immediately opposite to the oven, and to cireulate'from there horizontally around the upper portion of the outer lateral surface of the boiler or reservoir to and into the draft pipe or exitpassage l in one continuous fluespace, extending entirely around the whole lateral or upright surface and under the whole bottom of the reservoir or boiler, as in some of the old and formerly well-known ,but now nearly obsolete, saddle-bag stoves, and in others subse quently devised; and by thus making acookingstove with a fire-flue, E E, extended from under or along the oven, under thebottom got the reservoir or boiler, and up along that lateral surface end or side It only of the boiler or reservoir which is not nearest or immediately opposite to the oven to and into an exit-passage, I, the stove can be made of less metal and at a cheaper rate than a stove having an oven, a boiler or reservoir, and an exit-passage, all constructed and arranged together in like manner, but with a widely-expanded flue-space for the gases of combustion extended from under or along the oven entirely around the whole up right or lateral surface and bottom of the reservoir or boiler to and into the exit-passage; and by thus having a fire-flue, E E, extend from under or along the oven, under or across the bottom 9 of the reservoir or boiler,

and fro] .there up along the outer lateral surface or /side h of the boiler or reservoir into an exi passage, I, the said outer lateral surface or side h of the boiler or reservoir will receive more heat from the escaping gases of m'bnstion, and will be thereby heated to q're nearly the same degree as the side j,

hich is nearest or immediately opposite to he oven, than would be the case if the gases vof combustion passed from under or along the oven, first, under the bottom of the reservoir or boiler, and from there, up between the oven and the boiler or reservoir, directly into a draft-pipe or exit-passage.

I11 carrying out the aforesaid part of my invention I commonly apply heat to the inner side, j, of the boiler or reservoir, in addition to what that side receives from being immediately opposite to the oven, by any suitable means; for example, by having a fire -flue .space or fire-flue spaces between either the whole or a part of the contiguous and opposite sides 01 and j of the oven and the boiler or reservoir, so that the gases of combustion in such flue-space or flue-spaces shall be either in direct contact with that side j of the reservoir or boiler, or separated therefrom, either wholly or in part, by a casing or partition. (Indicated by dotted lines at w in Figs. 4 and 6.)

Another part of my invention consists in making a cooking-stove with a culinary boiler or hot-water reservoir arranged opposite to one upright side or end of an oven, and with a fire-flue or fire-fines extended down along that upright or lateral portion or side of the boiler or reservoir which is nearest or immediately opposite to the oven, and with a fireflue extended from under or along the oven, along, under, -or across the bottom of the boiler or reservoir, and up along that upright or lateral portion, side, or end only of the reservoir or boiler which is not nearest or immediately opposite to the oven, and into a draftpipe or exit-passage for the gases of combustion, all in such manner that the said boiler or reservoir shall be heated, first, by the hot gases of combustion passing down along and in contact with either the whole or a part of that upright side or portion of the boiler or reservoir which is nearest or immediately opposite to the oven; and, second, by the gases of combustion, in their passage from under or along the oven to and into the draft-pipe or exit-aperture, passing under and in contact with the bottom of the reservoir or boiler, and up, along, and in contact with that lateral side or portion only of the boiler or reservoir which is not nearest or immediately opposite to the oven.

In the aforesaid drawings of a cooking-stove embodying this part of my invention K L L are fire-fines extending down along that side j of the boiler or reservoir B which is laterally opposite to the oven A, and E E is a fire-flue extended from under or along the oven, along under the bottom 9 of the boiler or reservoir, and up along that lateral portion h only of the boiler or reservoir which is not immediately opposite to the oven, and into an exitpassage I.

By this part of my invention the boiler or reservoir itself is made to form a casing to the rear upright side of the descending fireflue or fire-fines L L K, between the oven and the boiler or reservoir, and is heated on the side j, which is immediately opposite to the oven, by some of the superfluous caloric of the intensely hot gases of combustion, which will pass down through the said fireflue or fire-flues between the boiler or reservoir and the oven; in addition to having its bottom g and outer side, h, heated by the gases of combustion in their final escape from under or along the oven through the fire-flue E E to the exit-passage I.

In carrying out my aforesaid invention I make the gas-flue E E of any suitable width in respect to the width of the bottom g and the outer portion, h, of the boiler or reservoir and arrange the top cooking-plate, fuel-chamher, and other flues of the stove in any suitable manner in respect to the oven, boiler or reservoir, and hereinbefore-specified fire-flue or fire-flues combined therewith. For example, in the stove shown by the annexed drawings, M is the fuel-chamber, from which the gases of combustion pass, first, into a fine space, N, between the top cooking-plate, O, and the top plate, 19, of the oven; and from there the gases of combustion pass, either down through the flue K, and thence directly into the flue E E,when the valve or damper Q is open, as in Fig. 6, or, when that damper is closed, as in Fig. 4, the hot gases will then pass down through the fines L L, and from their lower ends forward under the outer portions of the bottom plate, f, of the oven, and back through a central flue, R, and into the escape-flue E E.

What I claim as my invention, and desire to secure by Letters Patent, is

A three-fined cooking-stove having the central flue extended so as to inclose on the sides and bottom the culinary boiler or hot-water reservoir B, the latter being so arranged as to rest upon or against the edges of the sides of said central flue, so as to constitute the interior side or wall of the same, substantially as set forth.
